Virtual reality apparatus

Abstract

Provided is a virtual reality (VR) device, system and framework for generating VR continuum experience choreographed to a physical procedure incorporating at least one procedural action associated with a physical sensation and potentially inducing an anxiety or pain response. The VR continuum experience can modify perceptions of pain and anxiety associated with the procedure. The virtual reality device is configured to allow device control via a device user interface accessible to an operator other than the wearer (i.e. a medical practitioner), to allow the operator to control device calibration and virtual reality (VR) experience start while the apparatus is worn by the wearer, and to provide one or more VR experiences each associated with a physical procedure.

Description

TECHNICAL FIELD[0001]The technical field of the invention is apparatus and applications of virtual reality.BACKGROUND[0002]Virtual reality is a computer technology that uses head mounted goggles with a screen in front of the wearer's eyes and optionally speakers or headphones to provide an immersive and interactive user experience simulating a user's presence in an imaginary environment. Virtual reality (VR) headset movements are tracked to allow a user to “look around” in a three dimensional virtual world.[0003]Currently available VR devices typically include small stereoscopic displays, gyroscopes and motion sensors for movement tracking, and headphones or speakers. There are some known head mounts for smart phones to provide a VR experience using the smart phone. The smart phone is programmed with VR software utilising the device processor, display, gyroscopes, motion sensors, speakers etc. The head mount hold the smart phone in front of the wearers eyes such that the display is ...

AI Technical Summary

Benefits of technology

The patent describes a virtual reality device that allows a wearer to control the device and experience a virtual reality while undergoing a physical procedure. The device can be controlled by an operator through a user interface and can provide a VR experience that is calibrated for the wearer and the physical procedure. The VR experience can be designed to re-imagine the sensations experienced during the procedure and can influence the timing of the operator's actions. The device can be a mobile phone with a VR software application and a headset. The VR experience framework includes an order of execution for the procedural actions and a library of VR experience components for each action. The VR experience generation system includes a medical procedure library, a VR transposition resource library, and a VR experience compiler. The technical effects of the patent include improved training and preparation for medical procedures and improved patient experience during procedures.

Problems solved by technology

However, virtual reality systems developed for applications such as gaming or simulator training are typically designed for control by the wearer and not well adapted for interactive clinical situations.
